Isn't there ggc_alloc <T> for this? Also ggc_alloc_no_dtor<T> in case you

No, if I see correctly it only calls Dtor:
template<typename T>
inline T *
ggc_alloc (ALONE_CXX_MEM_STAT_INFO)
{
if (need_finalization_p<T> ())
return static_cast<T *> (ggc_internal_alloc (sizeof (T), finalize<T>, 0, 1
PASS_MEM_STAT));
else
return static_cast<T *> (ggc_internal_alloc (sizeof (T), NULL, 0, 1
PASS_MEM_STAT));
}
...
/* Allocate a chunk of memory of SIZE bytes. Its contents are undefined. */
void *
ggc_internal_alloc (size_t size, void (*f)(void *), size_t s, size_t n
MEM_STAT_DECL)
{
...
The function is generic, it does not know about type T. That's why it
does not (and can't call) ctor.
